Andronix
Short answer: yes, Termux itself is safe when you install it from an official source. It’s an open-source app from the Termux project, its code is public on GitHub, and it runs like any other Android app, inside Android’s app sandbox. The real risks are a fake Termux from an unofficial download site, and commands you paste into it without knowing what they do.
Andronix uses Termux to run Linux distros on Android, so here’s what you should know before installing it.
Andronix 10.1 doesn’t need Termux on most phones: it runs Linux right inside its own app. See Linux in the app.
What Termux is
Termux is a terminal app with a small Linux environment: a shell, and a package manager (pkg, built on apt) with thousands of command-line tools. It doesn’t need root and doesn’t change Android. Andronix runs full Linux distros like Debian and Ubuntu inside it.
What Termux can and can’t access
- Its own files. Everything you install in Termux lives in Termux’s private folder, like any app’s data.
- Your phone’s storage, only if you allow it. Termux asks for the storage permission when you run
termux-setup-storage. Until you say yes, it can’t see your photos or downloads. - The internet, to download packages and anything you ask it to.
- Not other apps’ data, and not system files. Termux runs as a normal app without root, so Android keeps it out of other apps’ private data and out of Android’s system, just like any other app.
Whatever you run inside Termux, including a Linux distro, gets the same access as Termux and no more.
Where to get it safely
Termux works on Android 7 and newer. The official sources, as listed by the Termux project:
| Source | Notes |
|---|---|
| F-Droid | F-Droid builds Termux from its public source code. A good default. |
| GitHub (the Termux project’s releases) | The Termux project publishes builds there. Its README warns that these APKs are signed with a test key shared with the community, so only download them from the official termux/termux-app repository. |
| Google Play | A current build for Android 11 and newer. The Termux project describes it as still under development, with some missing functionality and bugs. |
Two things to avoid:
- APK download sites and “modded” Termux builds. Anything not from the sources above can contain anything.
- The very old Google Play Termux (version 0.101, from 2020). Its package servers are gone, so it can’t install anything. Replace it with a current build.
The sources sign their APKs with different keys, so you can’t update one with another, and Termux add-ons that share its data (like Termux:API) must come from the same source as Termux. More: Install Termux.
Staying safe while you use it
- Know what you paste. A command you run in Termux can do anything Termux can: read its files, read your storage if you allowed it, and use the internet. Copy commands only from sources you trust.
- Install packages with
pkg. Termux’s package manager downloads from the Termux project’s repositories and checks them with the repositories’ signing keys. - Keep it updated:
pkg upgradeupdates Termux’s packages. - Only allow storage if you need it. Andronix’s distros use it to reach
/sdcard; if you don’t need that, you can skip it.
Is Andronix safe to use with Termux?
The andronix installer is downloaded by one command, and it checks the download against its published checksum before running. Linux distros are downloaded from Andronix’s servers or the distro’s official images and checked the same way. To get Termux, the Andronix app sends you to its official sources (F-Droid, GitHub and Google Play).
Everything Andronix installs lives in Termux’s folder, ~/.andronix/, and andronix remove <distro> deletes a distro completely. Nothing on Android is changed. See What is Andronix.
Common questions
Does Termux need root?
No. Termux, and Andronix’s Linux distros, run without root.
Why does Android warn me when I install Termux from F-Droid or GitHub?
Android asks for permission whenever you install an app from outside Google Play (“install unknown apps”). That’s a general warning about the source, not a finding about Termux. Allow it only for the app you’re installing from, such as F-Droid or your browser.
Can Termux see my passwords or other apps?
No. Termux can’t read other apps’ data. It only sees what’s in its own folder, and your phone’s shared storage if you allow it.
